,BOTTLE-FILLIN G VALVE.

To all whom it'may concern: ,=-Be it known that I, Roxanna Lrrrnau, a o izen of the United States, residing at lVestgrove, in the county of Chester and 'State of Pennsylvania, have invented new and useful V'IXHIJI'OVBIDGDS in Bottle-FilL :qng-Valves, of which-the following is a speci- 0 ion. I

his invention relatesi'to' in'iprovements in bottle filling valves and particularly to that class used ill-connection with machines adapted to operate on a plurality of bottles simultaneously. ltsfob ec'ts are: first, to provide a valve that will unerringly fill bottles full, irrespective of their holding capa'eity' or variations in the amount of liquid "which they may contain; secondly, to provide a filling means adaptable to any suitable filling machine construction, and finally to provide such fillin means so arranged that leakage or loss o? even when the tops ormouths of the bottles operated upon are chipped, irregular or rough and which will notcause breakage of theibottles, xcept by gro'ss misuse; these andalliedobj'ects are attainedby the mecha- 'nlsm hereinafterfully described and shown I in the accompanying. drawings, forming part of tliese specifications, and .in which:

Figure 1','is afront elevation, partially in I-scction, of the co'mnlete valve construct-ion, showing thesame closed. Fig. 2, is a simi- Ian view of the same, but shown as having been'turned through an angle of 90 degrees andthe valve infpesition to deliver -liquids.

Fig." '3-,is j a transverse sectional view, taken on ahline indicatedby characters. a a of F1g.1.-, Similar reference numerals refer to similar parts throughout the several views.

bar 17, is free to move up and down within-Q the slots 18, formedlongitudinally throughe the bushing 9, and casing-tube 2; the vvhole being so arranged-that. as the sleeve 11,-.is'

raised the point of the pin 16, contacts with the bar 17, thereby raising the valve 7, and

thus opening a' clear passage throughout the tube 2, at that time communicating directly with the bottle, the cap seat ofwhich is and 70 than tightly pressed against the ring:15, in the' I the same is more readily fitted into sleeve 11, which conveys vertical motion to it, and for the same reason part 16, is also made round and s t rigidlyinto the center of the valve 7 at its extreme lower end; while the same results might be obtained by combin=- mg partslti and 17, into one reversed T' shaped part, it would require far more-work in its construction, be more liable to disarrange eat and accomplish, at best, nomore e simple arrangementindicated.

In the foregoing construction it will'be seen that asfthe part sealing 'orforming joint contact with the bottle does not touch the upper part or end of the bottle'but rests Jon the inner, annular ledge therein, adaptu e .to receive the cap or bottle closure, that chipped, irregular or rough edges on the mouth of the bottle are immaterial so far as leakage is concerned, the joint being made interiorly and independent thereof; also that when the valve is closed, obviously all the liquid pressure is within the casing tube and. as there areno joints above the valve. no leaks can occur in the process of filling from either valve construction or from slightly defective or imperfectbottles' It -may also be noticed that the several parts can be readily dismounted'from the reservoir and disconnected from each other; that they are of suchishape as to .be thoroughly cleansedwithout the .use .of specialiipphances and that the liquid passes through a straight, uninterrupted .channel-ex cept for the valve scatand direct from the reservoir to the bottle; no packings, gaskets, etc, are

-used and that the liqu'id'does not come into' contact with springs or other parts difficult of access 1n the process of cleansing and anti-septic treatment.

In operation, one or more bottles, accord-' ing to the capacity of the machine, are placed upon a suitable table having means connected therewith for raising and lowering the same; said table being located directly'below the liquid reservoir and at a suitable distance therefromzwvhen the table is raised the bottles first make contact with the conical nozzle, which guides or centers them in register or aliuement with the rasing tubes; as the bottles rise, the semi-resilient annular rings enter the mouths, resting on the interior annular ledges or seats and forming tight joints therewith; further upwardmovement of the bottles causes thesleeves to slide upwardon the exterior of the tubesfagainst the pressure of the springs, bringing the bar set in the sleeve against the valve pin, raising the same and thus opening a clear passage therethrough; at the same time all air or gas contained in the bottles or entrained in the entering fluid, escapes through the 'vent tube, so that froth and bubbles are not caused. Thus notwith standing the holdin capacity of the bottles770 they will obviously Iiecome filled full to the level of the seat, minus the small and .constantly uniform quantity displaced by the conical nozzle.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent, is:

1. A bottle filling valve comprising a tubular casing, having a conical valve seat at its lower end, a valve loosely contained in said casing, fitted to said seat, a .stem attached to and extending above said valve, a vent tube positioned at one side and within the casing, connections between the vent tubeand valve stem wherebythe latter is; guided by the former, a sleeve slidable on the casing, a; resilient annular pad attached to the sleeve and adapted to cont-act with the seat formed interiorly of a bottle, an ertpansion spring surrounding the said casing and adapted to exert its tension againstthe sleeve downwart iv and means combined with the sleeve adapted to raise the valve upon raising the sleeve above a, certain point."

2. In combination with a bottle filling mechanism, comprising'a liquid containing .reservoir, of a hollow casing having means of connection with the bottom of the resera conical valve seat formed at 'the'lowerend of said casing, a gravity operated valve fitted thereto, said valve being'of lesser cross sectional area than the interiorfof .the casing, a sleeve slidable on the exterior of the casing 196 adapted tomake liquid tight'o'ontact witha bottle top, means to exert a tension on said sleeve toward the end of the casing, means to limit the movement of the sleeve downward and means combined with the sleeve "to raise the valve coincidently with raising the sleeve above a certain point.

In testimony whereof I have hereunto signed my name to this specification 1n the presence of two subscribing witnesses.
